Title: System for detecting the angular position of a moving body
IPC: G01S3/787
Filed: 1961-10-19
Abstract: 984,432. Moving body position finder. BOMBRINI PARODI-DELFINO S.p.A. Oct. 19, 1961 [Oct. 26, 1960], No. 37591/61. Heading H4D. The position of a moving body 1 (Fig. 1), provided with a light source is determined in terms of two orthogonal co-ordinates by means of apparatus comprising two photo-cells 4 detecting the images of the source in the fields 8 and 9 (Fig. 2) of two parallel telescopes 2. A generally opaque rotating disc 3 (Fig. 3) interposed between the telescopes and the photocells is arranged with four groups of transparent slits 15 adjacent its periphery for producing, by means of detector 6, a series of synchronizing pulse signals, for transmission to the moving body to cause the light source to radiate in a corresponding series of pulses. The disc is also arranged with four longer slits 14 which scan past the telescope images and pass on the light pulses from the source image when in line therewith. The width of the slits 15 and 14 are such that no more than two consecutive pulses can pass to the photo cells. The synchronizing pulse signals pass, together with the detected pulses from the photo-cells, to apparatus 5 wherein the synchronizing pulses corresponding to the detected pulses are blanked out, while those occurring thereafter in the same group, are made negative with respect to those occurring before. Algebraic addition of the thusaffected " before " and " after " synchronizing pulses gives indications of the body's position along two orthogonal axes, i.e. field 9 gives the X co-ordinate and field 8 gives the Y coordinate. The invention can be used to guide a moving body along the optical axis path of a telescope.

Abstract: 1398996 Photo-conductive detector circuits MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 14 Aug 1972 [12 Aug 1971 20 Dec 1971] 37748/72 Heading G1A A radiation responsive device designed to give a rapid change in the voltage-current characteristic as a result of a limited change in radiation intensity comprises a photo-conductive element in circuit with a negative resistance element. The latter may be a thermistor having a positive or a negative temperature coefficient, or a switching diode. In the case of a PTC thermistor whose characteristic is shown by curve 3, Fig. 2, increasing radiation intensities indicated by curves 4,5,6,7 would produce operating points 8,9,10,11,12. Thus, as shown in Fig. 3, a small increase in light intensity would produce a large drop in current. For decreasing intensities the series 12,11,13,9,8 would be followed. Similar pairs of graphs are given for the NTC thermistor and the switching diode circuits, Figs. 4, 5 and 6,7 (not shown). The switching diode can act as a memory device for intensities within the critical intensities. An example of an application of the detection circuit for controlling a relay is described, Fig. 9 (not shown). The detector may be in the receiver of a remote control arrangement. The radiation may be infrared.

Title: Apparatus and method for making non-woven pile material
IPC: D04H11/00
Filed: 1970-08-12
Abstract: 1311160 Pile fabrics MONSANTO CO 12 Aug 1970 [13 Aug 1969] 38908/70 Heading D1K A non-woven pile fabric is produced by arranging bundles 28 of parallel strands with the ends defining a planar face by means of tubes 31, which terminate in head 29, fusing the ends into a cohesive film-like backing 43, engaging the backing and withdrawing it from head 29, and severing the bundles of strands to form a film backed pile. Tubes 31 narrow in cross-section towards head 29 so that the bundles of strands are compacted, and frictional contact between bundles 28 and the inner walls of tubes 31 keep the bundles taut whilst they are severed. Alternatively, if low density strands are used to give a low density pile, each tube contains horizontally and vertically acting pairs of spring clamps (111, 112, 113, 114, Fig. 11, not shown). Strands of different colours may be arranged to form a pattern. Filaments, yarns, ribbons, tapes, tows, slivers, ropings or rovings may be of polyethylene, polypropylene, polycarbonate, polyurethane polystyrene, nylon 6, nylon 6, 6, polyethylene terephthalate, and copolymers of vinyl chloride and vinyl acetate or vinylidine chloride. The backing is made by fusing the ends of the bundles 28 by contact with surface 41 of hot plate 40. The backing may be stiffened by incorporation of a metal wire grill 50, supplied by magazine 53 before plate 40 melts the strands, which has selvedge loops (52, Fig. 8, not shown) extending outside the circumference of the backing to enable sections of pile fabric to be joined together. A plate of heat settable asphalt or rubber 56 may be applied to the molten backing to produce a semi-rigid pile-carrying block. The backing is drawn away by extraction plate 60, which is moved horizontally by cylinder 62. As shown, the horizontal movement of 60 controls the vertical movement of hot plate 40 by contact between roller 48 and sloping surface 67. Plate 60 comprises a plurality of horizontally extending metal bars. Some, 71, being horizontally movable relative to the other bars 72. Suction applied via slots 74 draws the still hot backing 43 onto a plurality of hooked barbs 78. Movement of plate 60 to the right orientates the polymer chains of backing 43 as well as withdrawing the backing and strands 28: An alternative extraction plate (85, Fig. 10, not shown) has a plurality of driven rotatable corkscrews (86). The extraction plate may have a contoured surface. After the backing 43 has been withdrawn a distance corresponding to the required pile length, the strands are severed by an endless band-saw blade 104, or by a wire, disk saw or laser beam. Stripper bars 71 then advance to strip the pile fabric from the extraction plate. Blade 104 and hot plate 40 may be combined in a heated blade (95, Fig. 6, not shown) which both cuts the strands and fuses the thus exposed ends, at intervals of twice the desired pile height. The pieces (102) are cut centrally into pile carrying pieces 21.
